The electronic properties of Ru-based active centers was regulated, and then the catalytic performance of the Ru-based catalyst for Sabatier reaction was effectively improved. In this process, it was verified by nuclear magnetic resonance spectroscopy Al-NMR) that urea doping ca...
The Sabatier reaction or Sabatier process involves the reaction of hydrogen with carbon dioxide at elevated temperatures (optimal 300-400 °C) and pressures in the presence of a nickel catalyst to produce methane and water. Optionally ruthenium on alumina (aluminum oxide) makes a more ...
The optimization goal was to maximize the space time yield by applying the systematic flux-oriented Elementary Process Function (EPF) methodology. The optimal temperature and concentration profiles along the reaction coordinate are first determined. After that they are approximated using two reaction ...

The Sabatier reaction (that is, CO2 methanation) is undergoing a revival for two main reasons. First, the power-to-gas concept offers the prospect of large-scale recycling of (point source) CO2 emissions, in combination with the use of large quantities of renewable energy to form methane. Wh...
A critical technological roadblock to the widespread adoption of proton-exchange membrane fuel cells is the development of highly active and durable platinum-based catalysts for accelerating the sluggish oxygen reduction reaction, which has largely relied on anecdotal discoveries so far. While the oxygen...
The use of the laboratory kit (Labscreen Mixed®) additionally requires a negative control serum (LabScreen Negative Control (LSNC) serum) in the anti-HLA antibody screening reaction. The serum is characterized by the manufacturer as being without anti-HLA class I antibodies and anti-HLA class ...
A solution containing 1 ml of a 0.1% (w/v) p-nitrophenyl β-D-cellobiopyranoside in distilled water; 1 ml distilled water; 1 ml 0.2M sodium acetate buffer, pH 5.0; 1 ml of appropriately diluted enzyme solution was incubated at 50° C. for 30 minutes. The enzyme reaction is stopped...
